Answer:

(2) exchange food, oxygen, and waste between

mother and fetus

Explanation:

In most mammals like humans, the fetus produced as a result of the fertilization of the sperm and egg, develops in the uterus or womb of the female. However, this developing fetus cannot yet fend for what it requires for survival and is still dependent on the mother e.g nutrients, oxygen etc. How do this substances get to the fetus? Here comes the role of the PLACENTA.

Placenta is an organ in the uterus that serves as a connection between the mother and the fetus in her womb. The placenta enables the mother to pass digested nutrients to the fetus and exchange gases (oxygen and Carbondioxide) between them via the umbilical cord. The placenta also enables the mother remove waste produced by the fetus into her bloodstream.

Some members of the Euglenids are photosynthetic, yet they will lose their photosynthetic pigment if left in the dark. True or F
irga5000 [103]

A) Some members of the Euglenoids lose their photosynthetic pigment when left in Dark : TRUE

B )The loss of photosynthetic pigment in Euglenids stored in the dark is permanent : False

<h3>What are Euglenas</h3>

Euglenas are unicellular organisms belonging to the kingdom Protista, when kept in the dark for too long Euglenoids begin to lose their chlorophyll. As it loses its chlorophyll it becomes unable to produce its own food and starts consuming bacterias within its habitat.

The loss of chlorophyll in Euglenids can be regained after it is been exposed to sunlight and allowed  to grow exponentially for several weeks.

Hence we can conclude that  Some members of the Euglenoids lose their photosynthetic pigment when left in Dark : TRUE  while The loss of photosynthetic pigment in Euglenids stored in the dark is permanent : False

based on the number of ATP generated during the electron transport chain for every one glucose molecule, how many atp would be g
OleMash [197]

Answer:

If 10 glucose molecules are broken down, 320 ATP molecules will be generated during the electron transport chain.

Explanation:

In the electron transport chain, high energy electrons travel across a series of proteins embedded in the inner mitochondrial membrane, releasing energy in the process.Hydrogen is pumped from the matrix into the intermembrane space, therefore an hydrogen ion gradient is formed across the inner membrane.These proton are then pumped back into the mitochondrial membrane where the synthesis of ATP from ATP synthase takes place.

In the electron transport chain, a total of 32 ATPs are generated per glucose molecule.

so if 10 glucose molecules are broken down:

1 glucose ⇒ 32 ATPs

10 glucose ⇒ 10*32

                       320 ATP molecules
